The company did not specific the problem in Uplay, but Gameranx reported that a vulnerability within the uPlay launcher allows hackers to trick the software into thinking a user owned a game that had not been purchased.

Hackers were apparently able to obtain an unreleased game, "Far Cry 3: Blood Dragon," although Ubisoft would not confirm that claim. Footage from the first-person shooter game was briefly posted on YouTube, but it has been removed.
